Title: Speaker device
Inventor: SHIMADA KOUSHIN
IPC: H04R3/04
Filed: 1982-11-15
Abstract: PURPOSE:To apply MFB without requiring a correcting equalizer by arranging concentrically a tweeter and a woofer and fitting a microphone to a center hole of the diaphragm of the tweeter or near the diaphragm so as to detect all bands of the reproducing sound of the speaker. CONSTITUTION:The microphone 10 provided at the center hole detects the reproduced sound of the tweeter 28 and the woofer 29 and applies feedback to a power amplifier 1 via a feedback circuit 4. Thus, since the microphone 10 detects a signal proportional to the acceleration of the speakers (28, 29), the acceleration feedback is applied, and the low reproduction limit frequency of the woofer 29 is reduced and the distortion is reduced by the amount of feedback. Since the effective acoustic center of the tweeter 28 and the woofer 29 is placed at the microphone 10, the reproducing sound detecting sensitivity of the tweeter 28 and the woofer 29 is almost, equal, and the equalizer for sensitivity correction required when the woofer 29 is located apart from the microphone 7 is not required.

Title: Simplified spectroscopy monitor for discharge cleaning
Inventor: OKAZAKI KIYOHIKO
IPC: G01N21/67
Filed: 1989-08-03
Abstract: PURPOSE:To use the light emitting intensity of a molecular beam as an index of the cleansing degree of the stain on the wall surface by separating and passing light from an optical fiber through an interference filter in the range of wavelengths of the molecular spectrum and detecting the passing light by a photomultiplier. CONSTITUTION:Light emitted by plasma which is ECR discharging is transferred from a monitoring window 11 of a vacuum container 10 to a detector 12 via an optical fiber 13. In the detector 12, the plasma light led through the fiber 13 is changed to parallel rays by a plano-convex lens 14. After the wavelength of the light is selected through interference by an interference filter 15, the parallel rays are condensed again by a convex lens 16. Subsequently, the spectral transmission light passing through the filter 15 is detected by a photomultiplier 17. An intensity signal of the molecular band spectrum in the band of spectral transmission is obtained by a recorder 18. In addition, the changing curve with time of the intensity signal is obtained.

Title: Electric/hydraulic governor device
Inventor: MIURA YOSHIMITSU
IPC: F01K7/38
Filed: 1990-07-30
Abstract: PURPOSE:To prevent abnormal increase of a pressure in a steam turbine in speed control after interrupting a load by selecting the higher value of an output of a speed control computer for computing a speed value of an extraction control valve and an output of a totally-opened biase computer while obtaining an opening command of the extraction control valve. CONSTITUTION:In case of an interruption of a load, a governing valve 2 and an extraction control valve are constantly and forcibly closed by a switch timer 21. When a turbine speed is higher than set value of a speed setter 10, switching is carried out to speed control. In respect to the governing valve 2 shifting to speed control is carried out by a speed deviation signal 11 between the set speed and a speed signal 9 under a closed condition. In respect to the extraction control valve 4, shifting to the speed control is carried out by a deviation signal 33 between a speed set value 32 obtained by adding a signal from a speed setting biaser 31 to the set speed and the speed signal 9 under a closed condition. When the value of the speed signal 9 approaches the rated speed, an opening command signal is output to the extraction governing valve 4. When a signal of a totally-opened biase computer 15 is gradually increased to be greater than a speed control signal, a totally-opened biase signal is selected by means of a high value selector 35, then the extraction governing valve 4 is gradually opened.

Title: Device for removing ferromagnetic coil spring from deposit and introducing it to treatment process
Inventor: HORUSUTO FURIIMERUTO
IPC: H05K13/02
Filed: 1981-12-14
Abstract: An arrangement for unscrambling ferromagnetic coil springs from a pile of coil springs, and conducting the coil springs to a work station. A cassette containing a disorganized pile of springs is provided with a first surface having openings, and discharge tubes associated therewith. A second surface which adjoins the first surface is provided with impact edges for controlling the upwardly vertical travel of the coil springs in response to a traveling electromagnetic field which, in one embodiment, is produced by a linear motor stator. The linear motor stator is arranged at an angle with respect to the second surface of the cassette, the apex of the acute angle being arranged at the junction between the first and second surfaces of the cassette. The traveling electromagnetic field attracts the springs to the second surface and causes them to travel upwardly until they encounter the impact edges. The inclination of the second surface with respect to the linear motor stator causes the springs to be conveyed into the discharge tubes.

Abstract: PURPOSE:To prevent deterioration of the cooling performance or warming performance of a vehicle air conditioner by reducing the quantity of air from a blower fan only when vehicle heat loads are judged to be within a predetermined range as switching from fresh air intake to inside air circulation is commanded. CONSTITUTION:An air quantity control means 104 controls the quantity of air from a blower fan 103 according to vehicle heat loads and reduces the quantity of air from the blower fan 103 when switching from fresh air introduction to inside air circulation is commanded. A judging means 105 then determines whether or not vehicle heat loads are within a predetermined range. The air quantity control means 104 reduces the quantity of air from the blower fan 103 only when the vehicle heat loads are judged to be within the predetermined range as switching from fresh air introduction to inside air circulation is commanded. Therefore when the vehicle heat loads are considerably high or low the quantity of air from the blower fan 103 is not reduced, so preventing deterioration of the cooling performance or warming performance of the vehicle air conditioner.

Title: Method of detecting crack and electrode for measuring potential
Inventor: KAWASE TAKAHARU
IPC: E21B47/00
Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To easily find a crack in the ground by forming a bore hole in the ground, laying the bore hole in water flowing state, measuring the underwater potential distribution laid along the bore hole, and determining the position having a specific distribution. SOLUTION: In the ground to detect the presence of a crack 3, a bore hole 1 is formed, and water is carried into the bore hole 1. When the water permeable crack 3 is present in the middle of the bore hole 1, the tomographic state around it is changed to change the potential distribution of water, and this position is detected as the crack 3. In order to eliminate the influence of potential distribution by a difference in geological structure, the water flow in the bore hole is stopped to measure the potential distribution of stationary water. The potential distributions in water flowing and stationary states are mutually compared, whereby the crack 3 can be more precisely detected from the specific potential distribution caused in water flowing time.  To measure the potential distribution, a reference electrode 21 is stopped within the bore hole 1, a probe electrode 22 is moved along the inside of the bore hole 1, and the potential in each position within the bore hole 1 is measured by a voltmeter 24.
